I have some Logitech Z-3s that I use with my Mini. I have the woodgrain one, but they make them in aluminum too. I know they make them in woodgrain and black/silver. A better version, Z-2300's, is all silver, might match. I would recommend these.
They look that they'd match the mini because they're white and aluminum. I have the woodgrain ones, as I said above. I got them for $30, so for the price they performance is unmatched. They are not worth $100, IMO. The bass is a little muddy, but they are great overall speakers.

I have the HK Soundstick IIs and I love them. They sound fantastick very crisp and clean. They also have that look that just says Macintosh!
You can get the Soundstick IIs for $104 at Provantage.com. I deal with Provantage all the time they are reputable and very fast shippers.

I will admit the looks of the Creatures match up with the Mini better. However, I listened to both the Creatures and the Soundsticks. IMO... The Soundstick IIs are by far the better sounding speaker of the two. Of course to be fair, they cost quite a bit more too._________________Mac Pro Quad 2.66GHz, PowerMac G5 2.3 GHz, iMac Core Duo 17", MacBook Pro 2GHz, MacBook Pro 2.2GHz, Mac mini Core 2 Duo 1.83GHz.

That's a great price until you add on the $21.95 ground shipping cost...

Brings it up to more than Amazon with free shipping.

But, thanks for the heads up though....

That is very strange, their shipping prices are usually right in line with everyone else. I just put the SoundSticks into the cart and they came up with $14.45 for shipping the Encounters came up with $12.95 shipping. I wonder why $21.95 for ground on the JBLs? Weight? Different warehouse? Mistake?_________________Mac Pro Quad 2.66GHz, PowerMac G5 2.3 GHz, iMac Core Duo 17", MacBook Pro 2GHz, MacBook Pro 2.2GHz, Mac mini Core 2 Duo 1.83GHz.
